2.4 Bonding and Thermochemistry
Atomic Structure
Electron Configuration
Bonding
Covalent
Covalent Network
A network of atoms held together with covalent bon
Ionic Bonding
Ionic Solids
Alternating postive and negative ions in a lattice
Metallic Bonding
Metal Solids
A lattice of postive nuclei in a 'sea' of electrons
Weak Intermolecular Forces
Molecular Solids
Molecules held together to form a solid with weak intermolecular forces
Properties of Solids
Solubility
"Like dissolves like"
Physical Properi
Physical Properties based on bonding
Hardness and Brittleness
Bonds repelling when under pressure
Bonds keeping connection under pressure
Malleability and Ductility
Abilty of bonds to flex and move while remaining bonded
Conductivity
Presence of free-moving charged particles
Melting and Boiling Points
Determined by the strength of the bonds holding the solid together
Low strength bonds = low M.P and B.P
High strength bonds = high M.P and BP
Energy Changes
Reactions gaining or releasing energy
Energy required = Endo
Bond making
Energy calculations
Energy release = Exothermic
Bond Breaking takes energy
